Speccaton of -Lei-,ters Patent.

Patented Sept. 26, 1905.

Application led January 30, 1905. Serial No. 243,192.

To cir/ZZ whomV t may concern: Be it known that I, JOHN A. HAIVILIN, of

Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers; and I do -hereby declare that the following is afull, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,and to the characters of reference marked thereon, which form part of this specification.

The object of my present invention is to provide an improvement in bottle-stoppers wherein provision is made for preventing the reflling of the bottleand which is simple and practical in construction and efficient in its operation. l v

In the drawingswhich accompany this speci- 'catiom Figure 1 shows a vertical section of the upper portion of the body, the neckportion of the bottle, and of the stopper and cork of my improved construction. Fig. 2 is a side elevation of the stopper removed from the neck of the bottle, Fig. 3 is a bottom view of the top portion or upper section of the bottlestopper. Fig. 4is a bottom or under View of the valve employed in the construction. Fig. 5 shows a modified form of construction of the bottle and' neck.

Referring to the reference letters and iigures in a more particular description, l indicates the body of the bottle provided with the neck 2, which is of a tapering form, particularlyas to its inner side or surface, with the enlarged end of the taper toward the or connecting onto the body ofthe bottle. The bottle-neck includes also a substantially cylindrical portion 2, adapted to receive the stopper and the cork. rlhe stopper consists of the three portions'or sections 3, 4, and 5, the two former being of ring shape, while the latter is a cap-like plate. The section 3 is provided with a shoulder adapted to rest on the inclined shoulder 6 at the point of juncture between the conical neck portion 2 of the bottle and the cylindrical portion 2a. The stoppersection 3 has an enlarged central opening, with a beveled or inclined valve-seat 3%.'A The-section 4 is of a ring form, having a relatively largev internal opening or perforation, together with an inwardly-standing ange'4, which may be given an upward turn, as shown.,

The upper section 5 is provided around its periphery with a series of small holes or openings 5tt to aord passage for the liquid from the bottle. lThe upper or cap portion 5 is also provided with a central socket 5b, which re ceives the upper end of the valve-stem 7*1 of i the valve 7. The opening in the middle'section 4 affords a passage for the valve-stem 7, aswell as for fluids around the stem. The valve-stem 7 is provided witha central longitudinal opening which, in connection with the socket 5b, receives the spring 8, said spring operatingto force the valve to closed position on the seat 3*, but still being ia light tension-y spring. The stopper parts 3 and 4 join each other with an inclined bearing-face, as indicated at' a, while the stopper. parts 4 and 5 ljoin each other with 'an inclined engaging face, as indicated at b. The parts4and 3 are arranged to afford a cavity for the open position of the valve, and the v alve'is limited in its opening movement by the top of the stem coming in contact with the bottom of the socket 5b, whereby it is prevented from closing the Vopening through the part or section 4 when in its open position. The upper section ofthe stopper has the edge or corner removed, and a groove c takes its place, and when in position with the lower end resting on the shoulder v6 the upper edge of the stopper takes a position opposite an internal -groove 0l in the cylindrical portion of the neck.

In practice it is found more advantageous to formA the stopper from glass, as well as the valve 7 and in order to facilitate suchmanufacture it is preferably formed in the sections 3, 4, and 5 fitting together with the inclined r shoulders a and t, as before mentioned. These will be ordinarily assembled in the form shown in Fig. 2 with the valve and stopper cemented together by some adhesive cement. In

this shapev they are in convenient form for use. The'bottle will be filled, of course, when the stopper is removed. When it.is desired to ,Y

close the bottle, itis preferably done as follows: Thev spherical weight 10, preferably" a glass ball, is first dropped into the bottle.- Then a thin coating of cement will be applied to the inclined shoulder on the lower end of the stopper and the stopper set in position,

lthe saidinclined shoulder resting on the shoulder 6. The cavity formed by the groove IOO d and the groove c will then be filled with some liquid cement and the same left to set. After it is set the cork stopper 9 will then be placed in position in the open end, substantially as shown.

While much has been said that the portion v2 of the bottle-neck is made cylindrical, this is not absolutely necessary and often a diiieult thing to accomplish Ain practice, and in this connection it should be noted thatin case the outer wall of the stopper does not engage the Vinner wall of the neck opposite thereto that when the liquid cement is introduced it will lill such a cavity as may be, even down to the shoulder 6. In some views of the device it may be advantageous to have the portion of the neck above the shouldei` 6 of slight conical form, with the larger end outward.

The most trying situation for devices of this class is when the bottle rests on its side. In this situation the conical form of the neck 2 will cause the weight l0 to roll away from the Astopper into the bottle and not interfere with the valve in its closed position.

The operation of discharging the contents of the bottle is quite obvious; but it may be mentioned that when the bottle is in inverted position and the cork stopper 9 having of course been previously removed the weight l0 will fall against the projecting bitted end 7b of the stopper and force it into open position. This allows the contents to flow through the passage, which then becomes free, issuing through the openings 5f. Vhen the bottle is turned into a horizontal position or to a vertical position, the weight l0 will fall away from the'stepper and allow the spring 8 to close the same. It may be noted in this connection that the flange 4a, standing opposite the opening 5, prevents the insertion of any instrument through the openings 5u to tamper with the closed position of the valve, also that when the flange 4LL is provided with an upward turn, as shown, it serves its purpose to better advantage than when simply made straight, as before suggested. It will also be noted that the spring 8, being entirely inclosed with the valve-stem and the socket 5b, is also protected from any instrument inserted through the opening 5a.

rI he stopper, consisting of the parts 3, 4, and 5, beingmade of glass, preferably, as before suggested, it will be noted that with an instrument, as a small punch and hammer, the whole stopper can be crushed and removed, whereby the bottle becomes useful for ordinary purposes in connection with a common cork stopper; but when so used it is evident fromthe absence of the glass stopper that it has been refilled.

In the modiiied form of construction shown in Fig. 5 the bottle-neck has been modified by forming a contracted opening n at the base of the neck, which is adapted to receive the weight 10 and prevent it falling into the body of the bottle when the body is in upright position. In this case, however, as in the former, the neck is made of conical form, whereby the weight is adapted to move away from the valve when the bottle is in a horizontal position.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of a bottle having a tapering neck enlarging toward the body, an internal shoulder in the neck, a stopper consisting of inner, outer and intermediate sections, the inner section having a large central opening and valve-seat for outwardly-opening valve, the outer section having a series of small openings arranged around the periphery and on the inner side a socket for the valve-stem, the intermediate section having` a large central opening affording a passage for the valve-stem and liquids and an in wardl y standing iiange alfording an obstruction in the line of the perforations of the outer section, a valve having a bitted projection projecting beyond the inner face of the stopper when seated, and a tubular stem engaging with the outer section, and a spring within the tubular stein for forcing the valve to closed position, and a weight incloscd within the bottle, substantially as set forth.

2. The combination of a bottle having a tubular outlet-opening with an internal shoulder adjacent to the inner end of the opening, a stopper seated on the shoulder and located within the opening consisting of three sections, the lower section having a central opening with a surroimding valve-seat, the middle section having an inwardly-standing iange 4, the top section having small pcrforations 5 vertically above the said ilange, an outwardly-opening valve 7 adapted to cooperate with said seat, a spring for forcing the valve to closed position conlined between the top and lower sections and a weight within the bottle adapted to engage and force the valve into open position when the bottle is inverted, substantially as set forth.

3. The combination of a bottle having a tubular outlet-opening with an internal shoulder adjacent to the inner end of the opening, a stopper seated on the shoulder and located within the opening consisting of three sections, the lower section having a central opening with a surrounding valve-seat, the middle section having an inwardly-standing iiange 4, the top section having small pcrforations 5a, vertically above the said flange, and a socket 5b, an outwardly-opening valve adapted to coperate with said seat having a bitted end operating in the opening in the lower section, and a tubular stein the upper end of which is received in said socket 5'), a spring IOO IIO
